Bug: 'SecTrustedApplicationCreateFromPath' is deprecated

[wuyahuang]

The build failed when trying to create a blog module on macOS.

cgo-gcc-prolog:203:11: warning: 'SecTrustedApplicationCreateFromPath' is deprecated: first deprecated in macOS 10.15 - No longer supported [-Wdeprecated-declarations]
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Security.framework/Headers/SecTrustedApplication.h:59:10: note: 'SecTrustedApplicationCreateFromPath' has been explicitly marked deprecated here

As @alexanderbez mentioned on Iusse 5759, cosmos-sdk depends on github.com/99designs/keyring and not keybase/go-keychain directly.

But keyring temporary fix the problem to get go-keychain compiling/testing, and the issue is still exists after 14 months.

Maybe it's time to switch from keyring to go-keychain, or just add a replace directive to go.mod.

replace github.com/keybase/go-keychain => github.com/99designs/go-keychain v0.0.0-20191008050251-8e49817e8af4
