Xcode 5 arm64 error

[pixelglow]

Thanks for the bug report!

Unfortunately I can't reproduce it with a minimal workspace in Xcode 5. In particular I successfully built a Release build for iOS Device with the settings:

• Base SDK: Latest iOS
• iOS Deployment Target: iOS 6.0

Please make up a minimal workspace containing the zipzap project and send it to me for further analysis.

Hi pixelglove, to reproduce the problem, you need to select "Standard architectures (including 64-bit)" in your project settings. This might be necessary if you want to include the new x64 slice in your library, to support the iPhone5s.
In order to build for x64 you need also to set 7.0 as the target ios.

@sgabello I can confirm the test workspace project's Architecture is set to "Standard architectures (including 64-bit)" and I see armv7 + armv7s + arm64 fat binaries being built.

I'd suggest trying the following:

• Use a workspace instead of a project at the top-level, and include zipzap and your original project under that workspace. Don't make zipzap a subproject of your actual project. We mainly support this configuration as noted in the README.
• Try building zipzap separately to include 64-bit and then link to the binary.
• Check to see if the latest zipzap library is linking. The podspec may reference an older zipzap library.

@pixelglow Can you set "Standard architectures (including 64-bit)" and still use iOS 6.0 as deployment target? This is really strange considering that in order to build a binary that supports both 32 and 64bit, you MUST use ios7 as deployment target. Check the documentation

I'm not saying this is a bug in zipzap. It's actually a requirement in xcode5 in order to build arm64 compatible binaries. So... with my comment I was actually trying to explain to @oscarvgg the reasons of his problem.

By using a workspace, everything should work correctly as long as iOS7 is selected as a deployment target.

On a side note though... I have to tell you that the other way to use the library, "As an independent project" (also noted as supported in the README), doesn't seem to work anymore. I couldn't find a way to build the library so that it includes all the arm architectures both for the simulator and device.

It may be that it works on Xcode 5.0.1, which is my current version. As your link states:

Note: A future version of Xcode will let you create a single app that supports the 32-bit runtime on iOS 6 and later, and that supports the 64-bit runtime on iOS 7.

Not really...
From the Release Notes:

Known Issues in Xcode 5.0.1 GM seed
General
In this seed, iOS 64-bit compatible applications are only supported with a minimum deployment target of iOS 7.

Oh well... I don't want to force you into believe what I'm saying :)
You might be lucky for real and be the only one able to build arm64 binaries with iOS 6.0 :)

@sgabello -- hmmm... perhaps it builds on Xcode 5.0.1 GM but it's not officially supported as yet.

In any case, I've just installed the public Xcode 5.0.1 (5A2053) and can confirm it builds my test workspace incorporating zipzap correctly. Their new release notes now say:

Able to build iOS 6 (32-bit) and iOS 7 (32-bit and 64-bit) binaries with a single build target

Do update to the public Xcode 5.0.1 and see if your build problems go away.

No further feedback, so I'm closing the issue.
