Xcode 15 is now 50% smaller on the Mac App Store, with downloadable simulator runtimes for all platforms. Enhanced code completion helps you write safer code faster, now referencing all your assets. And projects build faster thanks to improvements in the compiler and a brand-new linker, optimized for the multicore architecture of Apple silicon.
The new Bookmark navigator helps you keep track of landmarks in your code and organize your tasks. Localization assets are streamlined in the new String Catalog, giving you a centralized way to review and update them. And documentation shines in Xcode 15, with a beautiful new design, and real-time preview.
Swift, SwiftUI, and Xcode 15 work together as one. Powered by the new Swift macros, Xcode Previews are easier to use and now work across SwiftUI, UIKit, and AppKit. The new interactive timeline helps you develop and design your widgets. And working with different platforms and devices is easier: you can choose them right in the preview canvas to make sure your views look great everywhere.
Xcode 15 and Xcode Cloud work seamlessly together. Xcode Cloud is a continuous integration and delivery service built into Xcode and designed expressly for Apple developers. Start building your app in just a few minutes, with live build status, beautiful reports, and automatic distribution to your testers and users.
what is more annoying is that the super user responding to your obvious bug reporting does not seem to understand the actual issue. Perhaps try the work flow before responding and assuming we are idiots.
It's completely normal for the QR code information to disappear from your iPhone screen after you scan it. This is because the QR code acts like a quick key that unlocks the information it contains, like a website address or a downloadable file.
If you want to revisit the information encoded in the QR code, you'll typically need to scan it again. However, depending on the type of information, there might be other ways to access it as well. Here are some possibilities:
Open the Camera app from the Home Screen, Control Centre or Lock Screen. Select the rear-facing camera. Hold your device so that the QR code appears in the viewfinder in the Camera app. Your device will recognise the QR code and display a notification.
I'm also experiencing the same issue with my iPhone. Whenever I proceed to the payment process, the QR code vanishes from the screen, making it impossible to complete the transaction. Has anyone found a solution for this? It's really frustrating.
This is not with the intent of using in an app to be released to the app store - Basically I would like to solve problems on ProjectEuler using ARM and the iPhone, just for hobby and educational purposes.
1) write inline asm statements in C/C++/ObjC code, or2) write standalone assembly functions in a '.s' file and simply add it in your XCode sources, or3) write standalone assembly functions for an external assembler such as NASM. You write assembly code in a '.s' file and generate a '.o' object file using NASM and link the object file with your project in XCode.
So if you are just trying to write a few assembly instructions then inline assembler would be the easiest way, but if you plan on writing several assembly functions then I'd recommend a standalone assembly file. And if you plan on writing many assembly functions with macros and want cross-platform compatibility, etc, then I'd recommend using NASM to compile your assembly code into an object file. Because I am using the XCode gcc assembler and it is quite lacking compared to NASM. You can get NASM for free at
Once you have setup your assembler environment, you need to learn how to write ARM Assembly code! Because the iPhone (and many other portable devices and smartphones) use the ARM instruction set. There is a very good but old intro to ARM assembly at
When it comes to assembly programming, the official instruction set reference manual is usually the main source of information for everything you will write, so you should go to the ARM website and download the ARM and Thumb-2 Quick Reference Card (6 pages long) as well as the 2 full documents for your exact CPU.
You can use gcc to make asm inlines with __asm__, or just get a gnu as for arm and write code in separate files. You should have no problems with later linking them up to your project, but I'd suggest you to use c/Objective-C code to wrap up your asm stubs, as writing the whole iPhone application in assembler is somewhat hard (you need to be pretty good in ObjC runtime internals).
So, here is a quick description of how to actually include ARM asm code into an Xcode project, this is tested in Xcode versions up to 4.3. For my specific project, I wanted to define a function in ASM code saved with a filename like "decode_arm.s". I already have a C implementation of the same function that gets compiled when run under the simulator, so the conditional cpp logic here ensures that the ARM ASM code is only compiled into the project when actually compiling for the device.
Sometime in the last month or two the "Code from Message" function stopped working on my iPhone 12 (IOS 16.2 - 1Password for IOS 8.9.7). This happens on sites with a second factor required after using the normal username and password. Still works fine on my Mac laptop and desktop and my iPad.
Do you mean that when you receive a SMS text message that contains a one-time passcode it's not automatically suggested above your keyboard on your iPhone? If the answer is yes then 1Password actually isn't involved with this feature, it's handled entirely by iOS. You can read more about the feature here: Automatically fill in SMS passcodes on iPhone - Apple Support (CA)
If you set up 2-Step Verification, you can use the Google Authenticator app to generate codes to sign in to your Google Account. You can still generate codes without an internet connection or mobile service. Learn more about 2-Step Verification.
You can save your codes safely in your Google Account with Google Authenticator. This helps protect you from being locked out of your account when you change devices. However, you may instead choose to use Google Authenticator without these backup protections.
To edit your Authenticator code on iPhone and iPad, swipe left on any code to show the edit option. You can update the username for the code or change the associated Google Account where that code is saved.
If your device is lost or stolen, you should immediately ensure that any codes stored on the device cannot be accessed by others. To remove the codes, use the remote erase device option for iOS or Android. If this option is unavailable, you can choose between the following options:
The Solution is that you first delete the sync chain existing on the other devices you want to sync to the main one. Then the option to scan the sync code miraculously appears.
I just bought a new KP115 and during the setup process through the Kasa app it requires that I add it to Home, and I try to scan the code on the box and on the actual plug, though nothing ever happens. I do not really need to add it to my Home setup, I just want to use it through the Kasa app, though I can not until I get past this step. Any help will be appreciated.
Thank you for the feedback, if the phone failed to scan the QR code when set up HomeKit plug, you could try to adjust the direction of the phone, like use the phone horizontally or vertically to scan the QR code.
As far as I know the homekit set up is a step required by Apple, thank you for your suggestion with the HomeKit setup, i'd forward your suggestion with our team and see if any optimization can be done. If you have an Android mobile device
I have tried this with a new iPhone and a new iPad and when getting to the step where I am to scan the QR code, a rectangle appears that starts to outline the code and starts hopping around but never connects to anything. I also tried scanning the codes on the box. The two devices I bought are unusable until I get past this step. I also tried holding the phone close to where the code was and nothing worked. Is there any way around this step? Can you please show me an example of what one of these codes I am supposed to be scanning are? The only other possibility is that the devices I have do not have the correct type of codes on them?
Glad to hear from you, as far as I know the scanning QR code step is required by Apple and can not be avoided, unless you use an Android phone and go through the normal setup process. Can you use a phone to record a video and share the video here?
