The core concepts: workspaces, projects, targets, schemes,and run destinations


15/131


Effective use of the scheme actions


16/131



Working with build products


17/131




Scheme management


18/131




Scheme management

Workspaces

Projects Build configurations

Targets Build settings

Build phases

Build rules

Schemes Run destinations


21/131

Workspaces



Build phases

Build rules



22/131

Contains references to projectsand other files

Groups together projects you want

to use together

Provides a unique location for stateand build products

Allows implicit dependencies to befound between targets


23/131

Workspaces



Build phases

Build rules



24/131

References to source files

Targets which build products

Schemes which build targets andperform actions

Build configurations which selectvariants of target build settings


25/131

Build setting variants

Debug and Release are the default configurations

Build settings can have per-configuration variants

To vary build settings for another purpose, define a newbuild configuration

31/131

Instructions for building one product

References some or all sourcefiles in the project

Contains build phasesthe

high-level sequence of steps Build rules determine howto handle each file type

Build settings control howit is done

Can depend on one or moreother targets

Workspaces



Build phases

Build rules



54/131

Instructions for building targets and performing actions

Actions for running,testing, profiling, analyzing,and archiving products

A specification of targets tobuild for each action


55/131


56/131


57/131


58/131


59/131


60/131


61/131


62/131

Building is a step performed before each action

You always build with a purpose

The action you perform specifies targets and a configuration

The default Build command builds for the Run action

Workspaces

Build rules



68/131

The device you want to build for and run on


69/131

The device you want to build for and run on Choose among plugged-in iOS devices configured for development,available simulators, and the local Mac

Only devices compatible with your targets Base SDKand Deployment Target


70/131


71/131


72/131


73/131

Demo


74/131

What is an archive?

A timestamped bundle with: An install-style build of your application

Your applications debug symbols, in a separate dSYM file

Verification and submission status for your application Your own comments


75/131

Application archives

Contain only a single application

Archives containing anything else cannot be submitted to the Macor iOS App Store


76/131

Application archives

Your application should embed libraries and frameworks Static libraries are always incorporated into your application

Use a Copy Files build phase for frameworks and dynamic libraries

Turn on the Skip Install build setting for library and framework targets


77/131

Demo


78/131


79/131

Every workspace has its own derived data directory

Workspaces are distinguished by path Different copies of the same workspace have their own derived

data directories


80/131

Demo


81/131


82/131

Manually by the user

Automatically: When creating a new target or project

When opening a project or workspace for the first time
