# Installation iOS

We have 2 different methods for building for iOS:

1. Installation for an iOS Application using XCode (no Unity)\
   \- This will build an iOS app that only streams data
2. Installation for an iOS Deployed Unity App **(Unity Plugin)**\
   \- This will build a Unity AR iOS app so you can stream data while running an AR app

 Both will use the binaries we have already built for each platform and architecture. If you want to see how the binaries were built you can check out `3rdparty/build_ios_dep.sh`

To rebuild dependencies, in a git bash terminal

```
cd Sensor-Stream-Pipe/3rdparty
./buid_ios_dep.sh
```

This will download/build/install dependencies in a `tmp` directory. The result is a `*_ssp_iosdep.tar.gz` file.

## Building for an iOS App (no Unity)

### 1.0 Pre-Installation Requirements

1.1 Install [Xcode](https://developer.apple.com/xcode/)

1.2 Install Xcode command line tools

```
sudo xcode-select --install
```

1.3 Install cmake

```
brew install cmake
```

1.4 Install pkg-config

```
brew install pkg-config
```

### 2.0 Download and Install SSP

2.1 FOR DEVICE - To download and make iOS

```
git clone https://github.com/moetsi/Sensor-Stream-Pipe.git
cd Sensor-Stream-Pipe
mkdir build-ios && cd build-ios
cmake -G Xcode \
    -DCMAKE_TOOLCHAIN_FILE=../3rdparty/ios.toolchain.cmake \
    -DPLATFORM=OS64 \
    ..
open ssp.xcodeproj
```

### 3.0 Use it!

Now checkout Streaming [iOS ARKit RGB-D Data](/streaming-ios-arkit-rgb-d-data.md) to see how you can stream ARFrame data with Sensor Stream Server to Sensor Stream Client.

## Building for an iOS deployed Unity App (Unity Plugin)

### 1.0 Pre-Installation Requirements

1.1 Install [Xcode](https://developer.apple.com/xcode/)

1.2 Install Xcode command line tools

```
sudo xcode-select --install
```

1.3 Install cmake

```
brew install cmake
```

### 2.0 Download and Install SSP

2.1 To download and make iOS Device

```
git clone https://github.com/moetsi/Sensor-Stream-Pipe.git
cd Sensor-Stream-Pipe
mkdir build-ios && cd build-ios
cmake -G Xcode \
    -DCMAKE_TOOLCHAIN_FILE=../3rdparty/ios.toolchain.cmake \
    -DPLATFORM=OS64 \
    ..
cmake --build . --target unity --config Release
```

2.2 Moving the built libraries into the Unity Project

* Move the library built in build-ios/ssp\_plugin\_unity to the Assets/Plugins/iOS folder of the Unity project cloned in [this step](https://sensor-stream-pipe.moetsi.com/pages/-Mbhzo95saHrTRQ5f9nL#id-3.0-setup-unity-project)

{% hint style="info" %}
If you get this issue

<https://github.com/leetal/ios-cmake/issues/52>

Run this:

`sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer`
{% endhint %}

### 3.0 Use it!

Now checkout Streaming [iOS ARKit RGB-D Data](/streaming-ios-arkit-rgb-d-data.md) to see how you can stream ARFrame data with Sensor Stream Server to Sensor Stream Client.
