Description

Motivation and Context

[AliSoftware]

Addition of watchOS support would be cool indeed, thanks for the PR 👍

tbh, I'm surprised it would be compatible at all (like, is it possible now to emit requests via URLSession & all… directly from watchOS, not needing WatchConnectivity to ask the phone to do it for the watch? And thus for OHHTTPStubs to intercept them? I guess so, now that they introduced the latest AppleWatches… But I haven't done any watchOS development in a while and didn't follow that topic much, so probably a lot have changed that I didn't follow 😄

Waiting for you to finish the PR (CHANGELOG, tests, example project to show it at work…) to validate it 😉

[AliSoftware]

Please rename that file appropriately for consistency 😉

I'm a bit concerned if those changes are enough, as there is on several places code like #if defined(__IPHONE_7_0), that should be extended with __WATCHOS_2_0

[AliSoftware]

good point.

[linksmt]

Change name of watchos plist as suggested

[AliSoftware]

Ping @linksmt about the #if defined(__IPHONE_7_0) remark above 😉

[tfonfara]

I tried to come up with a solution by myself, but things are petty weird. I've added all necessary precompiler defines, but OHHTTPStubsProtocol isn't working properly.
canInitWithRequest is being called and also returns true, but neither initWithRequest nor startLoading gets called. I also tried with a simple approach in a fresh project to implement NSURLProtocol but found same behaviour.

Can you accept merge?
Thanks

@linksmt thank you for submitting this!

Everything looks great for the added target, but I think we should probably have some tests to go along with it so we can make sure we don't break it. 😄

Would you be comfortable adding some tests to the watchOS target?

I think it would also be helpful if you update the CHANGELOG.md to give yourself credit and update the original description of this PR.

Hi! @AliSoftware @linksmt, what is the status of this PR? I mean, OHHTTPStubs is still not supporting watchOS, doesn't it?
