Description

There is an issue with incremental builds on Xcode 12 / iOS 14:

[TRACE] /myproject/build/iphone/Classes/TiUtils+Addons.swift:10:8: error: no such module 'TitaniumKit'
[TRACE] import TitaniumKit
[TRACE]        ^
[...]
[ERROR] ** BUILD FAILED **
[ERROR] The following build commands failed:
[ERROR]         CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler
[ERROR]         CompileSwift normal x86_64 /myproject/build/iphone/Classes/TiUtils+Addons.swift
[ERROR] (2 failures)

It seems like the new Swift support with TiUtils+Addons.swift (TIMOB-28062) causes the issue. It may also affect iOS 13 / Xcode 11.x, but I haven't tested that, yet.

From the logs it appears that in the "Removing files" build stage we're nuking the Titanium.framework directory under Products/Debug-iphoneos/ which is then causing this error. I guess we need to unmark the file so it doesn't get removed
