[0245-tca-tour-pt3] Test case `testAddStandup` crash

[SunsetWan]

Steps to reproduce it

1. Open Standups project at git commit id f8a3513fac4e0949d729650c8b7c956c72e65f51
2. Run test case testAddStandup from test suite StandupsListTests
3. Crash!

Screenshots

Try to fix

I make this change to make the test case pass. It turns out that index 0 of $0.standups is valid. So I am confused about this crash 🧐 .

I'm facing the same crash. Looks like it is due to a change in the dependencies of TCA 1.0.0. In the video they are using swift-identified-collections 0.7.1 but if you take a look at the Package.swift file of version 1.0.0 it is pointing to "1.0.0" or greater. The workaround I found was to downgrade TCA from 1.0.0 to the previous version 0.59.0, which brings swift-identified-collections 0.8.0 and makes the tests pass. But we still need to know what is the change in swift-identified-collections that is causing this issue.

@david6p2 0.59.0 is a pretty old release. Can you point the app to as latest release as possible to see if the issue still persists?

@DominikGrodl I just tried with TCA 1.20.2 and the error persists. The problem is with TCA importing swift-identified-collections 1.1.1
