Step one: Download files
Download Ubuntu 15.10 Swift 2.2 Snapshot and Signature files. The downloaded files include swift-2.2-SNAPSHOT-2015-12-01-b-ubuntu15. 10.tar.gz and corresponding .sig files.
Step 2: Install dependencies
Use the shortcut keys Ctrl+Alt+T to open the terminal and install clang:
$ sudo apt-get install clang libicu -dev
Step 3: Import the new PGP key into the keyring of the Ubuntu system
$ gpg --keyserver hkp://pool.sks-keyservers.net \
p>--recv-keys \
'7463 A81A 4B2E EA1B 551F FBCF D441 C977 412B 37AD' \
'1BE1 E29A 084C B305 F397 D62A 9F59 7F4D 21A5 6D5F'
Step 4: Update signature verification
First, update the key certificate:
$ gpg --keyserver hkp://pool.sks-keyservers. net --refresh-keys Swift
Secondly, verify the signature authentication:
$ gpg --verify swift-
Note: The verification file is swift-
A warning may appear in this step, prompting the content as shown in the picture. Just ignore this warning.
Step 5: Unzip the file
$ tar xzf swift-
Here
Step 6: Add environment variables
$ export PATH=~/Documents/swift/swift-2.2-SNAPSHOT-2015-12-01-b-ubuntu15.10/usr /bin:${PATH}
The "~/Documents/swift/swift-2.2-SNAPSHOT-2015-12-01-b-ubuntu15.10" is the .tar.gz file decompressed on my computer the folder path after.
Note: The environment variables added here are only applicable in the current session and need to be added again the next time you reopen the terminal.
In order not to re-add the path every time, you can modify the ~/.bashrc file $ sudo vim ~/.bashrc
Add in the last line of the file:
export PATH=~/Documentation/swift/swift-2.2-SNAPSHOT-2015-12-01-b-ubuntu15.10/usr/bin:${PATH}
Note: If you have not installed the vim editor yet , can be installed via sudo apt-get install vim.
