Need amd64 target for Swift Package and Cocoapod

[wyllys66]

Trying to build a project that incorporates MailCore2 on a new Apple Silicon host (M1/M2/M3) with XCode 15 fails with errors like:

MailCore.framework/MailCore': found architecture 'x86_64', required architecture 'arm64'

I've tried using the cocoapod method and also the Swift Package method, both fail with variations of the same message. The default binaries used in these configurations does not include the latest architectures.

For now you have to exclude build of arm64 and use real device (this was my workaround), plus
add "-ld64" to "Other linker Flags".

I tried to run the scripts, but it failed 😞

I have filed a pull request to have SPM build from source: #2011. It no longer uses a binary and you should no longer face the issue you are facing.

If you wish to use the new Package, please use https://github.com/jsflax/mailcore2/ as your Swift Package dependency:

In Xcode click File -> Swift Packages -> Add Package Dependency...
Paste the following URL: https://github.com/jsflax/mailcore2
On the Choose Package Options screen, under Rules switch from Version to Branch (Branch: master) will be the default
Click Next -> Next -> Finish
