First off, I'm a Mac OSX newbie, both using and programming, but it's been thrust upon me. My project is moving along nicely, but I need to unzip a file, and it looks like SSZipArchive seems like the way to go. I want to manually add it to my project, so that it stays all together in my source code control system. Others, esp. the release engineer, shouldn't need to do anything, and we need to have all the source code local.
I've tried a million ways and back, only to keep getting the dreaded "No Such module" error. I've researched for a couple days now, and still no closer. So I'm starting from scratch in a new project to say what I'm doing and to plead for some help here. All this is being done on an El Capitan laptop, using Xcode 7.3.1, with Swift 2.2.
Create a Cocoa Application project, calling it 'ziptest', using Swift, nothing else checked. Build it just for fun.
Drag 'n' Drop the SSZipArchive folder found in the master.zip downloaded from the SSZipArchive GitHub site into my project. I'm not sure where it should go, or if it matters - top level, between ziptest project icon and the ziptest group or inside the ziptest group. But I'll put it inside the ziptest group. Now I'm faced with a new question - for the "Added folders", do I want to "Create groups" or "Create folder references". I do copy the items, because, as I said, I want to add them to SCCS later. I saw somewhere here on Stackexchange to make sure it is Group, so that's what I'll do. Build again and it still works.
I know I need a "bridging header" file, so I'll create it. I thought at some point, Xcode asked if I wanted to create it, but the above step doesn't do that. After much experimention, I found that if I d'n'd the SSZipArchive.m/.h files directly, it asks me. It doesn't put anything into it, but at least it creates it and updates the Build Settings. But I do this now manually by right clicking on the ziptest group folder, select New File... and create an empty Header File called "ziptest-Bridging-Header.h", following the pattern from the Xcode created one, being sure to check off the ziptest Target.
I add:
#import "SSZipArchive.h"
to that file. And building still works.
I added ziptest-Bridging-Header.h as the Objective-C Bridging Header in the Build Settings. And building still works.
Now comes the moment of truth. I add:
#import SSZipArchive
to AppDelegate.swift and I get the dreaded No such module 'SSZipArchive'
What am I doing wrong?
Edited to add: Oh, I also added libz.dylib to the Build Phases -> Link Binary With Libraries part. Doesn't help, of course, because we haven't even gotten to the link phase yet.

I've done a bit of swift, but I've never tried to use a third party package before. I created a brand new swift app, with Mac/iOS version and tests from the wizard. I went to xcode, right clicked on the sidebar, and chose add packages, and put in a package by url:
https://github.com/witekbobrowski/EPUBKit.git
It goes away for a little bit - and three package dependencies appear on my screen:
and when I look at my project settings, I can see them there:
(I actually added the zip package separately after the first one didn't work, just to test it, wondering whether something was wrong with the package)
Anyway - I can now see the packages, browse into them, see code or whatever - and the package found its own dependencies, so everything looks like it's working fine. But if I go into my swift app main, and add
import EPUBKit
or
import Zip
it just says "No such module ...".
I've obviously missed a step - what am I doing wrong - how do I fix it? I don't even know how to investigate it, because everything I look at just looks completely fine and I don't get any errors. I tried cleaning builds, restarting Xcode, using the real version of Xcode 13.2.1, using Xcode 13.3 beta - and nothing works.
NEW LEARNINGS
so - I tried changing how I'm running it to produce an IOS app - and it's working fine - but when I produce a Mac app, it's like the package isn't even there? Why would that be, and how do I make it work for Mac as well as IOS?
Author of EPUBKit here, thanks for taking interest in my library!
The issue is reproducible in a new project which kinda makes sense but don't at the same time. I am glad Xcode is not adding a package to every single target in my project but at the same time why does it assume that I want it in the iOS target? Anyway, I know that this question was already answered in the comment and the problem is solved but I might as well just drop more detailed instructions. Maybe it will help someone.
1. Select Project from Project Navigator
Select te target that is not working for you, in this case it's the macOS target. In the General tab you will see the Frameworks, Libraries, and Embedded Content section. If the package is missing from the list, tap the plus button at the bottom.
2. Add Missing Library
Look for the one you are missing, in this case its of course EPUBKit and tap the Add button.
3. Success
Now the library is successfully added to your target. Go ahead and build the project to run and enjoy your app :)
I am working on a Swift playground that contains multiple files in the Sources folder alongside the main file. When I type something, for instance, "UI", in the main file, I get the expected autocomplete suggestions. However, when I do the same in files in the Sources folder, I get a "dumb" autocomplete menu as seen in this question: Xcode 9 Autocomplete Not Working 100% - Partially Working
I have tried deleting DerivedData as suggested in the above question, and have even gone to the lengths of reinstalling Xcode entirely. However, the problem has not gone away. I have created a new playground to ensure it is not specific to this project, and the same problem occurs.
Edit: I just tried the same thing on a different Mac and the same problem was observed. I suppose this is simply a bug in Xcode that has nothing to do with this particular installation or project.
In order to enable autocompletion, you can embed your Playground in a regular Xcode project (e.g. an iOS application). I recommend creating a dummy project for that purpose. Simply drag and drop your playground in this dummy project and make sure to check "Add to target".
Then you can navigate to
Target -> Build Phases -> Compile Sources -> + -> Add other
and add all the files from your source folder. Please note, that you don't need to actually copy the files, a reference is enough for this purpose.
After this process all your source files are built against this dummy target and you can use autocompletion as usual. As far as I know, this is the best practice for debugging Playgrounds right now. Anyway I am curious, if there is an easier way to achieve that.
Swift playgroundbooks do not support autocomplete. Try writing the code in a regular Swift playground, and then move the code over to the playgroundbook.
This works for me every time,
Restart/Start -> Open any existing Xcode project(use autocomplete) -> Open playground
Autocomplete will work as usual
First of all I have to say that I'm new with Xcode and I found some things a bit comfusing for beginners.
For now I want to include SQLite support in my test app. I found the wrapper "FMDB" which seems very easy to use.
I was already able to include the .m and .h files into my project and setting the header line for bridging to Swift.
But if I build my app then I will get some link errors. I think the problem is that the sqlite library is missing. But I've no idea to include it. So I searched the web for some tutorials but all I found seems too old and didn't help me.
What I've already done are the following steps: I selected the top item of my project in the Project Explorer. Then I selected my build target and switched to the tab "Build Phases". But now I see no possibility to include the libsqlite.a file. I followed some suggestions and typed the keyword "sqlite" in the search field but I only get the message "No results found."
I'm using Xcode 8 + Swift 3 on Mac Sierra.
I think that U should find libsqlite.a file in the filesystem and only then add libsqlite.a to project by right click on project files in Xcode 8 and selecting "add files to " and select you .a library from system location like Homebrew's sqlite root folder, only then you can select this static library in "+" linking menu. Please read this answer:

I solved my problem by including sqlite3.c and sqlite3.h from sqlite.org so every wrapper works fine.
I just used Xcode's refactoring tool to rename a core data class from Player to Person. After fixing about 100 errors resulting from using dot notation that Xcode missed in the rename, I got to the last one:
Player.m - Lexical or Preprocessor issue - 'Person.h' not found
Player.m no longer exists in the project, and shows up as deleted (empty icon) in the error. Obviously, since I got rid of it, I don't want it to exist anymore!
To fix this, I have tried re-adding an old copy of Player.h and Player.m, and also cleaning. I have checked the Build Phases->Compile Sources section, and Person.m is there, Player.m is not. Person.h does in fact exist.
Not sure if it matters, but I am using mogenerator to generate my core data classes. Also, this is my third xcdatamodel version. Versions 1 and 2 used Player.h.
Here is a screenshot of the error:
Try clean build, if that doesn't work, restart Xcode, if that doesn't, delete the DerivedData directory, maybe even reboot.
Xcode sometimes gets confused.
You can try to do a super clean (not sure what the real term is) by hitting Cmd+Alt+Shift+K. This performs a clean and removes everything from the build folder.
Well I had a very similar problem and solve it removing the missing compile source of my project settings. to do that follow these steps
Click at the project page. This page contains the general settings
of your app
Select Build phases.
In Build Phases section, select compile sources.
If there is missing some class or file or something that needs to be compiled.
Select water mark file and click the minus sign at the bottom of this section.
Just click and the project may run. I hope this help others.
I am trying to create an app using three20 for a photo viewer. When I follow the instructions on their site (which is now simply running a python script) it seems to behave correctly but then when I try to build I get a "No such file or directory" error for using #import <Three20/Three20.h>.
I am pretty sure the header search path is correct, but I can't seem to get it working, even when I follow exact tutorials online.
Has anyone seen this problem before and know how to fix it?
Have you checked to make sure you actually have added three20 into your dir. as I remember having a similar problem, when I tried to use three20 which was due to the fact it wasn't in the right place, when I thought it was.
It sounds like you haven't imported the files correctly. Have another look at where you added the files to you project, if you have at all. (If not, you need to drag them into your project first!)
If you try to compile the project without the file added to the project, it will fail. Simply adding a path is not enough.
You need to drag it into Xcode...
Add it to the project...
And then your code should build.
I hope this helps!
