Swift Package Manager can't find module

Question

I'm trying to get familiar with Swift Package Manager. That's what I did:

1. • swift package init --type executable
2. • added a dependency in Package.swift
3. • swift build

And everything was fine, but after I tried to import Dependency in the code xcode says: no such module.

My Package.swift looks like:

import PackageDescription

let package = Package(
    name: "todo-bot",
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
        .package(url: "https://github.com/zmeyc/telegram-bot-swift.git", from: "0.0.0")
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.
        .target(
            named: "todo-bot",
            dependencies: ["telegram-bot-swift"]),
    ]
)

And when i try to build it without xcode it goes

• Compile Swift Module 'SwiftyJSON' (2 sources)
  • Compile Swift Module 'ScannerUtils' (2 sources)
  • Compile Swift Module 'TelegramBot' (135 sources)
  • Compile Swift Module 'todo_bot' (1 sources)

I have noticed this issue creep up on me today too. I followed the following steps to get rid of this error.

1. Close Xcode application
2. Delete the .xcodeproj file
3. Regenerate the packages again by running swift package generate-xcodeproj.

The next time you open the Xcode project the packages will be installed correctly and you won't have any build issues. Not sure this is going to help someone but I hope it does :)
