Reactivecocoa: I cannot run playground

[HanXiaoTeng]

I already build result,reactiveSwift and reactiveCocoa,and i open the ReactiveCocoa-ios.playground, but it still "run Sanbox" then "objc[15129]: pthread_rwlock_wrlock failed (11)"

[alper]

I did a fresh checkout and tried out the steps for the playground. I got stuck at the step:

Build ReactiveSwift-iOS scheme

This scheme seems to be geared towards a MacOS target and not an iOS one.

[sharplet]

@alper That can happen if you run checkout step while the workspace is already open in Xcode. Can you try closing Xcode and reopening it?

[alper]

• I deleted everything.
• Did a new checkout.
• Closed the playground and the workspace.
• Did the git submodule init
• Opened the workspace and started building, but ReactiveSwift-iOS still targets My Mac.

[alper]

I'm following the instructions from the playground.

I tried again from scratch and got the same result.

[ikesyo]

You may need this git submodule update --init --recursive. The missing --recursive option is important and that should be documentation bug.

[alper]

Ok. Now I'm further along, but now it can't find the built libraries.

(Also the playground is empty.)

Are you sure that you open (select) the playground within the workspace? Otherwise playground files can't find frameworks. That is a limitation or requirement of Xcode itself.

[alper]

Yes, I am. It still can't find them.

Guys, I unfortunately trapped into this problem although I taked the steps as the guide in the playground。 Here is the log ：

[akashivskyy]

Did you perform steps as described in an important comment on top of the playground?

[lizelu]

I clone https://github.com/ReactiveCocoa/ReactiveSwift.git Project, and perform setps as below。Result-Mac build success, but ReactiveSwift-macOS build fail. When I open ReactiveSwift.playground file, throw top error.

Retrieve the project dependencies using one of the following terminal commands from the ReactiveSwift project root directory:
git submodule update --init OR, if you have Carthage installed
carthage checkout --no-use-binaries

Open ReactiveSwift.xcworkspace
Build Result-Mac scheme
Build ReactiveSwift-macOS scheme
Finally open the ReactiveSwift.playground
Choose View > Show Debug Area

[andersio]

Make sure you open the playground within the workspace. Please also note that master requires Swift 3.1 and Xcode 8.3. If you are using Xcode 8.0 to 8.2, you should checkout the 1.1.3 release instead.

[lizelu]

I checkout the 1.1.3 release, It`s ok, thanks.
