Change in the frame rect of UIViews in storyboard when I open it in the XCode 11.5

I had done some application development in XCode 8.0 during 2015-16 and stoped after completing 90% due to some reasons. I wanted to continue that project and reopened it Xcode 11.5. When I opened storyboard in IB, I observed that the rects of almost all the views has been automatically changed. I can see it when I do file comparison in Sourcetree(below screenshot). I dont see any change in the display in simulators but worried about the impact. Storyboard has more than 40 VCs. Is it safe to merge this storyboard to develop OR I should do something to avoid auto corrections in the storyboard before merging it. Please provide some suggestions to continue. Thank you in advance.

This is how it looks like Sourcetree(git client for mac). In Bold is the change that has automatically occured.
  • <rect key="frame" x="20" y="254" width="245" height="30"/>

  • <rect key="frame" x="20" y="234" width="245" height="34"/>

<accessibility key="accessibilityConfiguration" hint="Enter your registered CTCA ID (email address)" label="CTCA ID"/>
  • <nil key="textColor"/>

<fontDescription key="fontDescription" name="HelveticaNeue-Medium" family="Helvetica Neue" pointSize="16"/>
<textInputTraits key="textInputTraits" autocorrectionType="no" spellCheckingType="no" keyboardType="emailAddress" returnKeyType="send"/>
</textField>
<textField opaque="NO" clipsSubviews="YES" contentMode="scaleToFill" contentHorizontalAlignment="left" contentVerticalAlignment="center" borderStyle="roundedRect" textAlignment="natural" clearsOnBeginEditing="YES" adjustsFontSizeToFit="NO" minimumFontSize="17" clearButtonMode="whileEditing" translatesAutoresizingMaskIntoConstraints="NO" id="1WD-1g-9bl">
  • <rect key="frame" x="20" y="318" width="245" height="30"/>

  • <rect key="frame" x="20" y="302" width="245" height="34"/>

<accessibility key="accessibilityConfiguration" hint="Enter your password here" label="Password"/>
  • <nil key="textColor"/>

<fontDescription key="fontDescription" name="HelveticaNeue-Medium" family="Helvetica Neue" pointSize="16"/>
<textInputTraits key="textInputTraits" autocorrectionType="no" spellCheckingType="no" returnKeyType="send" secureTextEntry="YES"/>
</textField>
<button opaque="NO" contentMode="scaleToFill" contentHorizontalAlignment="center" contentVerticalAlignment="center" buttonType="roundedRect" lineBreakMode="middleTruncation" translatesAutoresizingMaskIntoConstraints="NO" id="93i-ma-hHD">
  • <rect key="frame" x="87" y="426" width="146" height="29"/>

  • <rect key="frame" x="87" y="414" width="146" height="29"/>

It has been noticed that for labels, default height has been changed from 30 to 34, unless you have set a constraint.

I don't know of other solution that defining constraints in older Xcode before opening in Xcode 11.5.
