Hi Tico -

Thanks for the note - I'll look into it and report back to you on this thread.

Hi Tico -

I've been able to reproduce this warning, and the fix will go out with the next version of the iOS client, likely at the start of next week.

Thanks for the heads-up!

Hi I just wanted to report that I was also able to reproduce the same issue (and an additional crash on my iPad 1 with iOS 5.1.1), by downloading the firechat ios example at:

https://github.com/firebase/firechat-ios

And dropping in the newest fire bast ios SDK:

https://cdn.firebase.com/ObjC/Firebase.framework-LATEST.zip

Then adding:

SystemConfiguration.framework (same directory as Security.framework)
libc++.dylib (same directory as libicucore.dylib)

As per:

https://www.firebase.com/docs/ios-quickstart.html

----------

At this point there are no errors, but the project crashes in main in iOS Simulator 7.

Then I set:

-ObjC (other linker flags, aka OTHER_LD_FLAGS in project settings)

And it runs fine in the simulator, but causes the linker warning.

—————

When I run it on my iPad 1 with iOS 5.1.1 (9B206), it crashes in -[FRepoManager setQueue:] on 0x10ba48:

I tried both the iOS 5 and iOS 7 SDKs, thinking maybe it was a lib issue but there was no change. I’m thinking that perhaps firebase.framework is calling something that’s not in iOS 5?

So I was wondering if there is a version of the firebase iOS SDK that is compatible with 5.1, or would it be possible to make the next version support 5.1, or could this possibly be an unrelated issue?

Thanks,

Zack Morris

Hey Zack,

I was able to reproduce an issue when targeting iOS 5.1.  We'll take a look and see if we can get it fixed in the next release.

Thanks for the report!

Please notify me when the update is released, I am also having this problem.

[Michael Lehenbauer]

Hey guys,

The fix for the generateServerValues warning has just been released. You can grab the latest SDK here: https://cdn.firebase.com/ObjC/Firebase.framework-LATEST.zip

Thanks!

[Joao Roberto Sampaio]

I am having the same problem right now using the latest Firebase framework on iPad 1 with iOS 5.1.1. When it calls "initWithUrl" it strill crashes as mentioned above. Do you guys have an iOS 5.1.1 compatible framework somewhere?

Thanks

[Michael Lehenbauer]

Hi Joao,

Can you provide the exact error you're getting?  This is an old thread and there were several errors / warnings mentioned.

Thanks,

-Michael

Hi, Michael

When I make my Firebase app run on my iPad 1 with iOS 5.1.1, as soon as it reaches the line of "initWithUrl", it crashes. I opened a question on StackOverflow about this: http://stackoverflow.com/questions/29936366/firebase-initwithurl-crashes-on-ios-5-1

I tried to load an example app to make sure that it wasn't my app's fault so I downloaded the Firebase Chat app example and, on the same line (initWithUrl), it crashes exactly the same way.

I am using the latest Firebase version, 2.2.2. I tried downgrading to older versions but the problem persists.

This happens as soon as it reaches the Firebase *ref = [[Firebase alloc] initWithUrl:kFirebaseURL];

[Ack, resending since somehow the subject line got dropped.]

Hey Joao,

I synced up with some folks internally and unfortunately we've made code changes that are incompatible with iOS 5.x.  We're not planning to fix this, since usage seems to be very low (Apple lists 98% of users as being on iOS 7+).

You said you tried old versions of our SDK...  How far did you go back?  We have old versions back to 1.0.2 (iOS Changelog).  Perhaps one will work, though I honestly don't know, and unfortunately, I can't even test, since xCode doesn't support the iOS 5.x simulator anymore...

Sorry!

-Michael

Hello again, Michael

No problem.. I was using this iPad as a totem app for an event and I was planing to use a native application instead of a web based application (since I have better knowledge on this kind of development instead of the other one). I will try to roll back to the first one and see if this problem persists and then try to go increasing the version. Or else, I will just try to improve the web application and stay with it for a while.

Thanks for your time replying to this!
