Creating a lib without an example creates an Example directory

[sssilver]

$ pod lib create always creates a directory called Example and puts the workspace in it, even when asked not to create an example project.

Even if functionally this makes sense (a library needs a workspace to be opened in Xcode and worked on), semantically in this case the name "Example" is a nonsense.

Hi @sssilver,
This is intended behavior. As you can see in your output logs Putting demo application back in, you cannot do view tests without a host application.

If you don't want an example application you can't have view based testing as those require a host application.

Best,
Julian

[paulmelnikow]

Hmm, when view tests are turned off, the behavior is the same. It still creates an Example directory, even when no example project is requested.

[pejalo]

I also don't understand the directory structure. Every CocoaPod repo on GitHub has a .xcodeproj file in the root directory for editing and building source files. Where did this come from?

[dnkoutso]

The .xcodeproj is used for development by the developer. It can also be used if you decide not to use CocoaPods and just clone the repo as a submodule (or copy paste the contents) and then drag the .xcodeproj manually into your project.

The .podspec basically represents the same sources as the .xcodeproj but for CocoaPods. A lot of issues often arise due to this inconsistency and generally it would be great if the .xcodeproj is just generated by the .podspec instead.

[pejalo]

...or by pod lib create!

[inderdeep25]

has anyone found a solution to this yet ?

[jugutier]

TL;DR :

I only see the framework scheme (so no app target), so other than the name of the folder being example (and it not being too descriptive) I see no issues. If you add view based testing it'll add back the app target because it's required for view testing.

Let us know if there's still an issue. Otherwise we'll close this in a couple of days.

[revolter]

@jugutier, But isn't the MyLib.xcodeproj in the Example folder used as a demo application?

[teameh]

I'm struggling with this as well.

so other than the name of the folder being example (and it not being too descriptive) I see no issues.

Well it causes some confusion 😅

2 xcode projects are generated and a workspace that combine the 2 projects.

MyLib
├── Example
│   ├── MyLib.xcodeproj
│   ├── MyLib.xcworkspace
│   ├── Pods
│   │   ├── Pods.xcodeproj
... ... ...

So the workspace should be used for development? Sources of your pod can be found in the Pods.xcodeproj in Development Pods/MyLib? And tests in the other project in the workspace: MyLib.xcodeproj in Tests:

But then again:

• Why do these projects have 3 schemes and are 2 not shown by default?
• Why is the enabled scheme called MyLib-Example

[jugutier]

I’ll take another look at this tonight. Are you entering the same input to the interactive menu? @teameh

Hi @teameh

Sorry for the delay.

We'll change the folder name to something other than example (at least for this configuration) I think it definitely is confusing for that setup.

In the meantime yes, use the xcworkspace to develop and run pod install periodically in the test framework to make sure your podspec includes every file & asset the way you want.

Essentially MyLib.xcodeproj is a test framework target to which you pod install your local development pod. the xcworkspace holds both together so you can test and run the code as you develop it.

Let me know if that makes sense 👍

[teameh]

Yeah I think that makes sense. 👍

And maybe this is a bit off-topic... but I think it would also be nice if the pod lib create cli would (also) provide an option to scaffold a project with a fixed xcode project instead of a xcode project that is generated when you pod install the example app. I ran into a problem with creating a pod that required a build script to be ran during development (and not when compiled in users' app's). But if I add it to the generated xcode project it's gone every time I run pod install. It probably makes sense for most users to have this generated approach. but not for everyone.

[EdemAttiogbe]

Hi @jugutier

Any idea when the changes discussed with @teameh above will be implemented? As of Cocoapods version 1.5.3, the behavior above is still the same, and I can concur that it's really confusing.

Also, as an addition, when an example project is specified in the questionnaire presented by pod lib create, can there be two separate directory trees for both the example project and the actual pod? For example, something like below...

MyLib
├── MyLib.xcworkspace
├── Example
│ ├── MyLib.xcodeproj
├── MyLib
│ │ ├── Pods.xcodeproj
│ │ ├── Assets
│ │ ├── Classes

I never really understood why the Xcode workspace is within the 'Example' directory when it contains both the pod and example(if one is specified) projects.

No time frame I'm afraid, CocoaPods is just something people work on in their spare time - if you'd to see the change, you're welcome to take a look at shipping a PR 👍
