Wrap Content UILabel in xCode - ios

Question

I am trying to make a cell that will have two UILabels at the same line.
Like this:
User Name: blablabla
Where User Name is the first UILabel and blablabla is the second UILabel.
I want the first UILabel to be wrap content and the second one to have its content extended until the super view's trailing.
I tried to look for an answer to my question around StackOverflow, but I could not find one. Does someone know how can I achieve that?
I want something just like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/first_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="User Name:"/>
<TextView
android:id="#+id/second_label"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="bla bla bla"/>
</LinearLayout>
or like this
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/first_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="User Name:"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
<TextView
android:id="#+id/second_label"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="bla bla bla"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toRightOf="#id/first_label"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
</android.support.constraint.ConstraintLayout>

Answer 1

Try to change content compression resistance priority
Look at these snapshots:
Labels with default content compression resistance priority
I changed content compression resistance priority for label blablabla blablabla, from 750 to 749.

you can do this by :

Answer 3

You should try the following solution.
For first label.
Add top, left, bottom, width constraint.
Now set number of lines to 0 and Autoshrink to Minimum font size shown as below. You should set your required minimum font size.
For second label
Add top, left, bottom, right.
Now set number of lines to 0 and Autoshrink to Minimum font size shown as below. You should set your required minimum font size.
These changes will make first label's font autoshirnk upto your minimum font size. And will also make the second label to extent the content.
