Error after converting to Swift 5 and updating pods to recommended settings

React Native Lesson 6.3 (TaskApp)

I probably messed up badly by following Xcode's suggestion to convert to Swift 5 and update pods to recommended settings. Before, the app ran perfectly, but now it gives the build error Typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t') in the file Time.h (Pods/RCT-Folly/Time.h).
Here is the entire code in the Time.h file. (The part which Xcode highlighted as the error was the part typedef uint8_t clockid_t;):

// OSX is a pain. The XCode 8 SDK always declares clock_gettime

// solve that by pretending we have it here in the header and
// then enable our implementation on the source side so that

I read online that the error was related to React Native, though the given solution (which was to disable something called Flipper) did not help.
I'd appreciate it if someone could reverse the convert and update or fix the error to build and run my app.

Hi, can you try:

cd ios
pod deintegrate && pod setup && pod install

in your VSCode terminal?

[RWCoding58]

Thanks, I can run it perfectly with Xcode now. Although, when I run it in the terminal, it gives a build error. I'm not sure if it's related to the previous one, but at least I have a way to run it without it giving an error.

Not sure about your terminal, but at least you can run it with Xcode!
