Errors when trying out Gmail Sample App for IOS in Swift
Sreekumar Kodakara
I tried the instructions in the sample App from this link. https://developers.google.com/gmail/api/quickstart/ios?ver=swift. I encountered several problems. Can someone take a look at the documentation and let me know what I need to do to get this app working? I tried this in Xcode 7.2 and older version of XCode (6.3+). I got the same results in both.
These are the problems with the documentation that I encountered:
1. Step 3.b: The file mentioned in the step google-api-objectivec-client/Source/GTL.xcodeproj does not exist.
2. Step 3.d: The build target GTLTouchStaticLib does not exist.
3. Step 3.e and 3.f is not required (those files/build targets) do not exist
4. Step 4.d Supporting Files group does not exist
5. There are two Step 4 (Step 4 prepare the project, Step 4: Setup Sample)
6. The sample code in Step 4: Setup Sample has compile errors at this statement
7. output.autoresizingMask = UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleWidth
8. I was able to search around and get the problems resolved above the best I could. But at the final step, I got these linker errors. I am not sure how to get around this one.
