- Debugger*
- Cross-Compiler
- Linker*
Software Development Kit (SDK) for the target platform including:
- Emulator or simulator
- Platform specific debug service
- Platform libraries and source code or header files
- Other build and platform relevant tools
Version Control System*, e.g. Git, SVN
Test-Tools*, e.g. HockeyApp (Test-Distribution)
Collaboration and Project Management Software*, e.g. Podio, Slack, Trello, Taiga, Jira
Continuous Integration Tools*, e.g. Jenkins

(*only available on Apple macOs)

Different CPUs have different instruction sets
In order to run an application on a certain processor it has to be compiled to the machine code corresponding to the processors Application Binary Interface (ABI)

Simulator	Emulator
Software that imitates the behavior of a software system by providing the same set of interfaces as the simulated software	Software that imitates the behavior of a computer device or other electronic system

Supports collaboration, i.e. development of source code in a team
Stores different versions of a software efficiently without using too much storage space
Allows to restore older versions
Efficient backup tool for you work

Subversion client for Windows (next to the command line interface)
- TortoiseSVN: http://tortoisesvn.net
  - Seamless integration in Windows Explorer
Subversion for Mac (next to the commandline interface)
- E.g. Eclipse Plugin Subclipse http://subclipse.tigris.org (also Windows)
Git client for Mac & Windows (next to the command line interface)
- Atlassian SourceTree: http://www.sourcetreeapp.com (free)
IDE integrations:
- Android Studio
- Xcode

use git if	use SVN if
There are multiple independent groups of developers that can contribute to the project, AND/OR	All your developers work under single management, AND
It is difficult to provide all developers with fast access to a central server	All developers can get relatively fast access to a central server

Development procedure where changes are integrated frequently into a repository
Principles
- Maintain a code repository
- Automate the build
- Test the build automatically
- Daily commit of every developer & build including test of every commit
  - Keep the build fast (otherwise it would take too long for CI)
  - Testing is done in a realistic but not productive environment (clone)
Automate deployment for user tests
- Make it easy for developers & testers to access the latest builds and see the build results
- Also called Continuous Delivery (CD)

Some advantages of CI
- Bugs can be found and fixed immediately
- Due to frequent builds, integration problems can be fixed at an early stage (reducing debug time)
- Can increase code quality
Disadvantages of CI
- Initial setup is time consuming
- Good test-tools are required
Tools for CI
- Jenkins, OpenSource CI tool written in Java (forked from Hudson)
