Theos is a cross-platform suite of development tools for managing, developing, and deploying iOS software without the use of Xcode. This tag might also refer to an operating system originally authored in the 1970's.
Theos is a cross-platform suite of development tools for managing, developing, and deploying iOS software without the use of Xcode. It is community-driven and managed. One popular way of using it is to patch/modify system or non-system applications, where such modifications are popularly known as tweaks. Tweaks can be used in ways comparable to tools like frida and mobile substrate in jailbroken devices. In fact, Theos uses the capabilities of mobile substrate as the engine powering tweaks, but provides templates, tools and the Logos syntax, to make tweak development more convenient. Theos can be used directly on iOS devices to build tweaks, on or MacOS, e.g., to build the tweaks and package them in .deb packages that can be installed on iOS devices.
